A large well defined right suprarenal mass lesion that is separated from the liver by a rim of fat is seen (best appreciated in portovenous phase). The lesion demonstrates heterogeneous contrast enhancement with areas of cystic changes/necrosis. It is of note that the lesion tends to enhance more during the portovenous phase with retained contrast during the delayed phase.
The rest of the scan was unremarkable.
Giving the radiological appearance and clinical presentation of uncontrolled hypertension pheochromocytoma is the best fitting diagnosis.
